ALVIN G. SHERMAN, OF DETROIT, MICHIGAN, ASSIGNOR TO THE DETROIT VAPORSTOVE COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICIHGAN' STOVESTRUCTURE Application filed January This invention relates tostovestructure and has to do particularly with the fabrication, constructionand assembly of that portion of a stove or range which surrounds thegrate structure, namely, the back splash member, the side splash member,the means for supporting the grates, the drip pan and the warmingchamber or cutlery drawer.

Heretofore, in the construction of gas and vapor stoves, the generaltrend has been towards completely enameled stoves, designs andconstructions which make for cleanliness and sanitation. However, in

present construction, the so-called top of the stove or frame whichsupports the grate structure is usually made of cast iron, and isusually so formed as to present joints that will soon fill up withgreaseand dirt and make it practically impossible to clean the stove.

It is the object of the present invention. to provide a novel form ofback' splash and front member for the stove top in combina tion with anovel gratestructure, whereby a space will be provided between the gratetion of the back splash member directly above the normal grate lineextends rearwardly from the usual position of the back splash member.This construction not only helps materially in the fabrication andassembly of the oven in relation to the back splash member. but alsopresents a very unique design for the exposed part of the back splashmember in that it extends rearwardlv of the normal line of the backsplash member in gracef ul curves, and furthermore it directly combineswith the support of the grates in that portions of the back splashmember adjacent the level of the grates are pressed out to and s, 1930;Serial No. 419,408.

form relatively small supporting legs, whereby the corners of each gratemember are supported, and leaving the space in between entirely free.Furthermore, this pressed out back splash member continues downwardlypast the level of the grates and then converges inwardly to a pointabove and within the contour of the drip pan.

A further feature of the present invention resides in the constructionof the side splash member which extends directly downwardly past theedge of the grate member and converges inwardly to a position above thedrip pan, fr0m which position it again extends outwardly and co-operateswith the side wall of the warming chamber or cutlery drawer to form atrack or runway for the drip pan,

A- still further feature of this side splash member is the manner inwhich such member is pressed out and fabricated to receive the fuelconduit leading to the oven burners.

Another feature of the present invention resides in the fabrication andarrangement of the side portion of the stove top adjacent the outeredge, and the front structure of the stove top. This side structure isso fabricated that it converges inwardly similar to the side splashmember, and also co-operates with the Wall of the warming chamber toform the other track for the drip pan. The front end of the side memberco-operates with the front part of the stove structure to support thesame, the other end of the stove structure being supported by the sidesplash member or side Wall of the oven. This front stove member is notonly so fabricated as to support the front end of the grates similarlyto the back splash member, but it also extends forwardly to form thefront apron of the stove; or, in other words, the front apron of thestove is so formed as to form the front part of the stove top and tosupportthe grates.

Other features of the invention will be obvious from the specificationand claims.

Fig. 7 is a sectional view taken on the line 77 of Fig. 1 andillustrating the manner of assembling the back splash member and theside member of the stove top.

Fig. 8 is an enlarged fragmentary sectional View illustrating theformation of and the manner of connecting the side member of the stovetop and the side member of the warming chamber to form a track for thedrlp pan. ,The present invention is pecuharly adapted to that type ofstove known as gas or vapor ranges, the standard types of which are pro-7 vided with suitable oven and broiler casing,

- the oven, a stove top including a frame for.

a back splash member flush with the back of supporting the grate, and aseparate chamber or housing posltioned beneath the drip pan.

The present invention therefore relates. to the standard type of gas orvapor range, but has particularly to do with the fabrication ofpractically all the parts adjacent the stove top. In Fig. 3 I have showna plan view of a stove top embodying the present invention, and alsoshowing a portion of the oven wall adjacent thereto. This stove top isso different from the standard top construction that it can only bereferred to generally as a stove top as really the to is formed by theside and back splash mem ers and the front a ron.

The back splash member may be generally designated 1. Its constructionis best illustrated in Figs. 2 and 3. Referring to Fig. 3,

the sides of the back splash member may be designated 2 and 3. Fig. 3being a section taken on the line 33 of Fig. 1, it will be obvious thatthe side 3 of the back splash member is of special formation at thepoint of section. but that the side 3 takes a regular maestro form as at4, in Fig. 7, below the shelf sup port 5. j a

As best shown in Fig. 2, the top edge or flange of the back splashmember may be designated 6, and the extreme bottom flange 7. This backsplash member is preferably formed from a single sheet of sheet metal ina single stamping operation, whereby the dished out portion 8 is formedtogether with the flanges, as above set forth. This dished out portion 8of course has the outer edges thereof preferably provided with a smoothcurve where it joins the side and top flanges.

The forming'of the side flange 2 makes it very easy to assemble the backsplash member with the back and side walls of the oven, such assemblybetween the flange 2, the back wall 9 of the oven, and the side wall 10of the oven, being best shown in- Fig. 3.

Due to the pressed out or dished out portion 8 of the back splashmember, it will be seen that the back of this splash member extendsrearwardly of the .back wall 9 of the oven. This extension isapproximately of the same depth as the exhaust flue for the stove,whereby the spacewhich is ordinarily wasted when the stove is positionedagainst v the wall is taken up by this dished out portion 8 of the backsplash member.

The bottom part of this back splash member 1 gradually curves inwardlyas shown at 11 in Figs. 2 and 5, whereby such curved in portion 11terminates at a point 12 above and within the contour defined by thedrip pan 13. The inwardly curved portion 11 is then ofi'set, as shown,to form the flange 7 which co-operates with a suitable shell 14 tocomplete the back wall of the stove. This back splash member is alsopreferably formed with pressed out lugs 15 and 16 at the cornersthereof, and a lug 17 centrally thereof. Such lugs 15, 16 and 17 arepreferably formed in the same horizontal plane, so as to form supportsfor the grates, as will be presently described.

The oven wall 10 or side splash member of the stove is preferablyfabricated as a single unit, and also extends inwardly towards splashmember 10, adjacent the point where the burner conduit 24 enters theoven, is preferably pressed out so as to form a flat vertical surface 25for receiving the flanges of the burner manifold conduits. Thisstructure is best shown in Fig. 6.

The opposite side of the stove structure from the oven wall 10 is formedby a sheet metal shell member 26. This shell member '1 l I It will thusbe seen that I have provided is preferably curved inwardly .as at 27 tocorrespond with the curved in portion 18 of the splash member 10, and isalso formed to provide a flange 28 which cooperates with the flange andshelf member 29 to form a second track 30 for receiving the other sideof the drip pan. The rear portion of the side member 26 is so fabricatedas to be secured to the flange 4 of the back splash member 1, and thefront end of this side member 26 is provided with a down-turned flange31, whereby it may be secured to the front member or front apron of thestove.

It will thus be seen that the rearwardly bulged out back splash member,the side splash member, and theouter side wall of the stove, all areinwardly curved at the lower ends, whereby to terminate at' a pointabove and within the contour defined by the drip pan, and also to form atrack for receiving and sup orting the drip pan.

T e front of the stove is provided with acombination apron and frontmember, which may be generally designated 32. This member 32 consists ofthe flat horizontal top portion 33, and flange 34 which extends downwardly at right angles and then outwardly to form a ledge for receivingthe grates. Thisapron or front member is adapted to extend past thewalls 10 and 26 as best shown in Fig. 3 and suitable lugs 35 and 36 areprovided at the front of the oven and the front of the side frame, asbest shown in Figs. 2 and 3,

' for receiving and supporting this entire apron unit. Suitable flangesare preferably secured to the under. part of the apron and are pro videdwith slots for fitting around the lugs 35 and 36, as best shown in Fig.2.

'The top portion 33 of the front member 32 preferably extends forwardlyand downwardly around the manifold 37 to form a front shell or apron 38,which partially covers the manifold and valve mechanism of thestove.

The lugs 15, 16 and 17 on the back splash member and the flange34 on thefront member are preferably'so designed as to receive a grate structure,such as diagrammatically illustrated at 39, Figs. 1 and 2. The gratestructure, as best shown in Fig. 3, is preferably provided with cornerpro ections which cooperate with the lugs on the back splash member andon the front member, whereby to form spaces between said corner proections which extend completely around the grate members. It will thusbe seen that the grate members are not only solelysupported by the backsplash member and front member to make the same easily removable andincrease the simplicity of assembly, but that also a relatively largespace is provided which extends substantially around the'grates toeliminate all grease anddirt collecting crevices,l and to permit easycleaning at the grate eve a novelstove structure including a back splash1 member, a side splash member, a combined front member and apron, and aside member, which are so designed, fabricated and arranged as togreatly reduce the number of parts of the stove structure, and to permiteasy, quick, and inexpensive assembly. The

pressed out back splash member not only .of the stove structure areformed in'a novel manner-to provide tracks for the drip pan, but hasnothing whatsoever to do with the supporting or positioning of the gratemembers. The front part of the stove completes the stove top and assistsin completely eliminating the standard stove top frame, in that thefront is so fabricated as to form the front of the stove, support thegrates, and to cover up the manifold and valve structure.

The apron 32 not only covers up a great part of the manifold and valvestructure, but being removable gimply by lifting the same off of thelugs .35 and 36 this permits accessibility to the manifold and alsogreatly sim plifies the front of the burner casing. A suitable shield 40may be positioned beneath the flange 34 of the apron member whereby all.

four sides of the burner casing as formed by the panels 10, 11, 26 and40 will present smooth, easy accessible surfaces of pleasing appearance.1 It will furthermore be obvious that by providing a dished-out portion8 and by positioning the apron 32 completely in front of the stovestructure that a much 'deeper stove unit is provided with the resultthat the manifolds of the burner members may be made of the requiredlength as required by manufacturing codes, thus making it unnecessary toobtain length by bending the manifold conduits. To give the drip panunusual strength, the edges are curled over as best shown inFigs. 1 and2 and these curled 'over edges greatly assist in giving the drip paneasy slidability. Theinterior surfaces of the top shelf .and the sidebracket also conform to the smooth contour of the back splash member, asbest shown' in Figs. 1 and 2.
